Název v původním jazyce

The support affects the catalytic conversion in thymol hydrogenation reaction

Popis výsledku v původním jazyce

Hydrogenation of the aromatic ring in phenolic compounds is an important reaction in industry and in the synthesis of fine chemicals. Pd-supported catalysts have proved to be highly active and efficient in deep hydrogenation of aromatic ring. Previous studies confirmed that the acidity and topology properties of the support play an important role in the efficient transformation of the phenolic reactant. In this study, we have investigated the effect of these two parameters by designing advanced layered MFI and MWW zeolites. To understand the effect of acidity, we compared the catalytic performance of a series of Pd/MFI catalysts that significantly differed in the acidity of the support. Then, we compared the catalytic results from Pd on aluminosilicate MFI and Pd/ MCM-56 to see the effect of the support&apos;s topology. Thymol was used as a model phenolic reactant, and the results confirmed that not only the Pd on non-acidic MFI support was inactive (conversions below 25 %), but also the acidity of the MFI support led to higher thymol conversion (47 %), while more weak acid centers and silanol groups in dealuminated MFI topped up the outcome (100 % conversion). Data also showed that between two aluminosilicate supports, the MWW outperformed MFI (100 % vs. 47 %), due to its topology and morphology for better accommodating thymol and interacting with it.
